본 발명은 실란트층 및 흡음재층을 포함하는 타이어에 관한 것으로서, 타이어는 타이어 내측에 위치하는 흡음재층, 타이어 내측면과 흡음재층 사이에 위치하며, 타이어 내측면에 도포된 실란트층, 그리고 흡음재층과 실란트층 사이에 위치하는 필름층을 포함한다. 상기 타이어는 타이어 내측면에 도포된 실란트층에 의하여 펑크 발생시 자가 봉합을 할 수 있으면서도, 흡음재를 포함하여 소음 저감 성능을 가지며, 못이 타이어와 실란트를 관통하여 흡음재에 도달시에도 흡음재의 미세 조각이 실란트의 기능을 저하시키는 것을 방지하고 소음 저감 성능도 유지할 수 있다.

    The present disclosure relates to a tire comprising a sealant layer and an acoustic absorbent layer, and the tire comprises an acoustic absorbent layer positioned inside the tire, a sealant layer positioned between the inner surface of the tire and the acoustic absorbent layer, and applied to the inner surface of the tire, and a film layer positioned between the acoustic absorbent layer and the sealant layer.The tire may enable a sealant layer applied to the inner surface of the tire to perform a self-sealing process in case of puncture, may have the noise reduction performance by comprising an acoustic absorbent, and not only may prevent micro-fragments of the acoustic absorbent from deteriorating the function of the sealant, but also may maintain the noise reduction performance even when a nail reaches the acoustic absorbent by penetrating the tire and a sealant.
